MAROllS L. HORTON, OF WINDSOR, VERMONT.

Specification formingpart of Letters Patent No. 115,320, dated May 30, 1871.

To all to whom these presents shall come:

Be it known that I, MARCUS L. HORTON, of Windsor,.in the county of Windsor and State of Vermont, have invented certain new and useful Improvements in Steam-Boilers, of

which the following is a specification:

`My invention relates toa Wash-boiler having a single interior receptacle for the articles to be cleansed, which receptacle is provided with an elevated pierced bottom for the circulation of water, andone or more steam-pipes `leading to a supplementary steam and condensing chamber, having a pierced bottom to secure a perfect circulation of steam and the return of the water of condensation to there- In the drawing making part of this specification, Figures l and 2 are vertical sections,

a and Fig. 3 a horizontal section of a steamboiler embodying my improvements.

A is the clothes-receptacle. Bis the elevated perforated bottom thereof. G is the D yis the upper or steam E is the perforated-bottom to cov- H is the outer boiler or jacket.

The interior vessel in .all its parts, as well` as the outer boiler, may be constructed of j tinned iron in the ordinary manner when del signed for household use, or may be made of copper orboiler-iron when designed-for hotel j or laundry use; `and. the method of operating it is as follows: I first place the soiled or unbleachedV articles in the receptacle; I then place the cover initsvproper position and fastenit securely down by sliding the bolts; -I then fil] the cuter boileror jacket, which may f be of any shape, butwhich I prefer `of the same general form as the receptacle, and not l greatly larger, with" coldor warm water sufficient to extend `to the top cover of the receptacle when the latter is placed therein; I then a place the covered receptacle in the boiler and subjectl the whole to heat by placing it upon a stove or range. As soon as steam begins to form a current of steam ascends through the tubes into the chamber; a portion of it is here condensed and runs forward into the receptacle, while the uncondensed remainder issues in numerous jets through the perforations in. the bottom of cover directly upon'the articles cape into the apartment.

l By my `invention I find that a very high degree of heat can be maintained in the apparatus without danger of explosion and-.without serious inconvenienceor annoyance arising from escaping steam. The whole interior receptacle, with its contents, acts as a safetyvalve, permitting a very considerable pressure of steam, and rising to emit steam before 'a `point of danger can be reached, While the agitation of ebullition, added to that exerted by the jets of steam from above and below, speedily dissolves the accumulations in the articles to be cleaned, and is found to act with great rapidity in removing the coloring matter from unbleached goods which it is desirable to whiten. v

Ololflm. a

I claim- Y The construction and arrangement of the chambers G and D, connected by one or more steam-pipes attached to the perforated bottom B of the receptaela and Passing through the: f

perforated bottom E of cover, the whole arranged substantially as and forthe purposes herein specified.
